Ang Omega Centauri (ω Cen, NGC 5139, Caldwell 80, o Melotte 118) ay isang pabilog na kumpol ng bituin sa konstelasyon ng Centaurus na natuklasan ni Edmond Halley noong 1677.[1] Ito ay matatagpuan sa layong 15,800 taong-liwanag (4,850 parsecs).[2][3]

Ito ang pinakamalaking kilalang pabilog na kumpol ng bituin sa Ariwanas na may diyametrong humigit-kumulang nasa 150 taong-liwanag.[4][5] Tinatayang naglalaman ito ng humigit-kumulang nasa 10 milyong bituin at may 4 milyong masa ng araw.[1][6][7]

May mga ipinapakita ng ebidensya na may isang bihirang itim na butas na may katamtamang masa (intermediate-mass black hole) sa gitna nito, kasama ang mas maliliit na itim na butas na kasinlaki ng bituin (stellar-mass black hole), at natukoy ito sa pamamagitan ng astrometriya.[8][9][10][11][12]
